Figure 3 is a sectional view on the line 3-3 of Figure I looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates portions of channeled sills forming runways of the hydraulic lift employed at service stations for the hoisting of motor vehicles and of standard construction. Disposed upon the lifting cylinder or jack B of the lift and disposed transversely with respect to the sills A of the latter is a support I0. This support may be arranged in a greasing pit or at a service station, garage or the like if desired, or it may be: otherwise 1o- I6 cated. Upon the support I 0 are suitable bearings H in which is journaled a driven shaft 12 which extends into frame [3 of a stand mounted upon and rising from the support ID at one end thereof. This stand is of the required make-up and carries an electric motor. [4- constituting the power source for thelapparatus and its driving shaft l5 carries a gear l6 meshing with a gear l1, its shaft l8 being suitably journaled in the stand and carrying a worm screw IS; The worm 25, screw I9 is in mesh with the worm gear 20 upon a shaft 2| which is also journaledin said stand; The shaft 217 carries a pinion 22 meshing with a gear 23 on the shaft l2, so that the latter is driven from the motor I4, as should'be apparent.

Upon: the shaft I'Z between therunways A are fixed a series of peripherally grooved eccentric rollers or wheels 24",, such" series being arranged at opposite sides of the longitudinal center of the lift and the said shaft [2 is preferably'located medially with. respect to the length of the lift. Adapted to be changeably engaged with the series of rollers or wheels 2 1' in the peripheral grooves 25 thereof are jacks 25 having spring pressed bearing posts 21 provided with the pointed tips 28 for biting engagement with the side sills 29: of a motor vehicle, these tips being adapted to effect a hold-fast engagement with the said sills, and the jacks 26 carry handholds or grips30; so'thatlthey can be conveniently placed and handled. Each' jack 28 carries a saddle base 31, for fitting in straddling, relation the rollers or wheels 24, the selective engagement of the jacks 26 being at the option of the user thereof and for the purpose of accommodating such jacks to the motor vehicle chassis-according to the size of the vehicle. These jacks under the action of therseries' of rollers or wheels 24, one series being set reversely to the other series in their fixed relation: upon=the shaft I122, will alternately raise 55 will open so that lubricant or grease may be delivered therebetween, and in this manner these springs can be quickly and effectively lubricated.

It is understood, ofcourse, that the motor vehicle is directed onto, the rack or lift, its wheels following the channeled runways A of such lift,

as iscommon. The bearing posts 2! at their tips 28 willassure positive engagement of the jacks 26 with the side sills 29 of the chassis of the motor vehicle and on the rocking and liftingof such vehicle there is no liability of the slipping j of the chassis or'the jack to avoidfreeing of the I latter while beingoperat'ed upon by the series of wheels or rollers 24 which have a cam action upon 'the'jacks in the working of the apparatus.

'sCarried atIone end ofithe' shaft I'Z is azdisk having the eccentric wrist pin .48 with which istconnected a piston rod 49,its piston operating within-a purnp} cylinder -55 for lubricant, the

piston being indicatedat 5i, and said' cylinder having the inlet and outlet branches 52 and 53, respectively, at opposite sidesthereof. The inlet branch 52, through the medium ofthe coupling nipple54, hasiconnection with a lubricant supply conduit or lead 55. The branch 53, through the coupling nipple 56, has'connection withlan outlet or deliverypipe 5'! for lubricating service in the lubrication of the equipment' ofi the motor vehicle 'when' the apparatusvis in use. I V

.The branches '52 and 53 have arranged therein spring controlled return check valves, 53, these being of standard kind. It is; of course, understood-that the lubricant supply lead o'r'conduit 55 hasfitted therewith a suitable cut-off valve (not shown) to regulate or. shut off' the :feed

of lubricant to the pump and likewise the electric circuit to the motor 14 includes aisuitable switch (not shown) for starting and stopping said motor. l

7 On theframe l3. of the stand is a table top59 and ipassed' through a suitableopening therein islpairocking 'levenfilLhavinga 'ballbearing 6i removable. within a seat 62 therefor within the top 59. .;The lower end ofithe lever 60 engages in a camgroove. 63.-.in,a,cam wheel 54 fixed to the shaft l2, while'lthe upper end of the lever-has connection ,with a spring equalizer 65 which,

. through the rod 66 andclip'l carried thereby,

is adapted for attachment to. the steering wheel 43.0fthe motor vehicle and the purpose therefor .is togive a turning motion to the steering mechanism, 'wherebytight or loose. parts in its equipment can, be detected, adjustments. made and a complete and thorough lubrication attained.

7 end ofthe lever 600m its disengagement from the" =..Upon'the frame,l3 of'the stand are brackets 168; these being located on opposite sides of the path of movement of the lever 69 and carrying cupped rests 69 for accommodating the lower cam wheel 64, this being effected by manually lifting the leverwhich extracts its ball bearing -6lfrom its seat62 and the placing of the lower end of this lever in either of the rests69 and thus rendering saidlever' passive or inactive and also permittingithedisconnection of the clip 61' from the .wheeljdS or-for'theinitial attachment of the clip with said wheel. V i. Theicylinder for lubricant has threaded in :itsjhead T0 the lower .end of a swinging rod'H "which carries a bearing ball 12 "fitted Within" a seat 13 inthe top 59 of the stand. The rod has sufficient play in the top of the frame so that it isreciprocable. The rod II extends above the top 59 and active against the under side of this tip is a coiled compression spring 14 which functions to normally hold the ball seated. The compression spring 14 at its lower end is engaged upon an abutment 15 in the form of adjustable jam nuts on said rod and the other end of the spring plays against the under face of thetop 59.

When the disk 41 is rotated the piston is operated in an outward direction to cause a suction stroke with lubricant entering the cylinder past check value 58 on the right, (Figure 2) the cylinder 50 pivoting about the ball 12 during such stroke. 'When the piston starts on its inward or discharge stroke beginning 180 degrees from the position in Figure 2 the inlet valve 58 on the right is closed and if the outlet from the conduit 51 is open the'lubricant will be forced therethrough past check valve 58 on the left; f?

In the-event that the outlet fro'm'conduit 51. is' closed the piston andiits-cylinder will move-inunison (the grease being incompressible) -the {rod H being forced upwardly through the seat-=13; thereby compressing the-spring M. On the downward stroke, if conduit-51 is stillclosed; the spring returns'the cylinder and. pi'stoninunison without drawing any lubricant through the lead 55.- .This latter operation: continues without drawing-in or discharging any lubricant during continued rotation of the disk 41,}until the outlet isopened to allow discha'rgefromithe cylinder.

' 'Theapparatus'in the use thereof enables movement to be imparted to a motor vehicle similar to those when the vehicle is in motion up'on a. road and therefrom therelcan bereadily detected any: defects in the parts-"of thelworking of the vehicle, "such. as loosenessQtightness or" irregularitylin fittings of the equipment of the vehicle,
